Designed for use in environments where explosive gases or dust may be present, the LEDLENSER EX7R Intrinsically Safe Rechargeable LED Flashlight delivers up to 220 lumens of white light without the hassle and expense of disposable batteries. The EX7R is certified safe by ATEX for Ex-Zone 1/21 environments. LEDLENSER's Advanced Focus System allows you to switch between a wide flood beam for area lighting and a narrow spot beam for concentrated light in smaller spaces or viewing at a distance. The light is controlled by a sliding side-mounted switch with low and high power positions, bracketed by off positions at either end for convenience. A full charge in the included cradle will power the light for 10 hours on high power and 45 hours on low. It's IP66-rated water resistant and dust-tight.
